Personal Essay Options

For my personal essay I haven't quite decided what to write about yet. I have had a few experiences that I think impacted me and made me who I am today such as my cousin moving in with us under foster care, and when i challenged myself to the fullest this summer and created a mural from scratch to paint on my baby cousin's bedroom wall. I am not sure which one to choose to write about because one changed me as a person where as the other experience just made me realize what I can do when I actually try.
